An investigation of sorption kinetics of heavy metal ions on polysaccharide materials has been performed. Traditionally, kinetic study of ion exchange sorption begins with a determination of the slowest stage of the proces, but the stage of chemical reaction between heavy metal ions and the sorbent functional groups can also make essential contribution. Results of kinetic studies were treated using different kinetic models and, experimental data are described most adequately with pseudo-second order kinetic model. It is determined that polysaccharide materials used in the studies have relatively good kinetic characteristics.
